LOCK Foe SASHES.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed July 15, 1905. Serial No, 269,846-

To all whom it may concern:

Be it known that I, OHARLEs B. OoNAN'r, a citizen of the United States, residing at Adrian, in the county of Lenawee and State of Michigan, have invented a new and useful Lock for Sashes, of which the following is a specification.

- This invention relates to looks, and while more especially adapted for use as a sash-lock, in which connection it is shown and described, is well adapted for use in other positions.

The object of the invention is to provide a lock embodying new and improved features of cheapness, convenience, and reliability.

A further object of the invention is to provide a lock which may be easily and quickly applied even by one not skilled in handling tools.

A further object of the invention is to provide a lock having a spring-actuated sliding bolt controlled by a key and the bolt of which is held withdrawn by the key when once turned until manually released.

A further object of the invention is to provide a lock having a sliding bolt which carries at its outer end an axial spur to automatically indicate the center of the bore necessary for the receipt of the bolt, as in a window-casing.

A further object of the invention is to provide a lock having a cylindrical casing proportioned to fit Within the bore of an ordinary auger and having longitudinal beads to engage the grain of the wood and secure the lock against rotary displacement.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a perspective view of a rail of a window-sash with theimproved lock mounted therein. Fig. 2 is a perspective View of the lock removed from its mounting and with one semicylindrical casing member removed. Fig. 3 is a transverse sectional view of a sash-rail and longitudinal sectional view of the lock mounted therein. Fig. 4: is a longitudinal sectional view of a sash-rail and a transverse sectional view of the lock mounted therein. Fig. 5 is a perspective view of the sliding bolt, showing its rigidly-attached collar and disk.

Like characters of reference indicate corresponding parts in all of the figures of the drawings.

In its preferred embodiment the improved lock forming the subject-matter of this application comprises a cylindrical casing, (indicated as a whole by and composed of semicy lindrical members 11 and 12.) To one end of the casing member 11 is rigidly secured a partition or diaphragm 13, and secured to said casing at a point intermediate its ends is a second diaphragm 1 1. The diaphragms 13 and 14: are provided with lugs 15 and 16, respectively, which engage suitable openings 17 and 18, formed in the casing member 12, the two casing members being secured together by u psetting the lugs. The casing member 12 is provided along its longitudinal edges with outturned flanges 19, forming a longitudinal bead throughout the length of the casing and upon opposite sides thereof.

The diaphragms 13 and 14 are respectively provided with registering eccentric openings 20 and 21, in which is slidably mounted a bolt 22, having at its rearward end a disk 23, rigidly and eccentrically secured thereto and approximating in size the interior diameter of the casing 10. .The bolt 22 is likewise provided with a rigid collar 24, and a spring 25 encircles the bolt and bears-at its opposite ends against the diaphragm 14 and the collar 24:. At its outer extremity the bolt 22 is provided with an axial spur 26, proportioned to be contained within the casing 10 without the diaphragm 13 when the bolt is drawn, as clearly shown in Fig. 3.

The casing member 12 is provided with a keyhole 27, and the sash-rail is provided with a registering aperture 28, through which is inserted a key 29, and an escutcheon of usual form may be secured thereover in the usual manner.

It will be noted that the casing 10, being cylindrical in form, is adapted to fit an ordinary auger-bore, and the beads 19, extending radially therefrom, will engage the grain of the wood, as shown in Figs. 1 and 4:, and prevent the rotary displacement of the casing. The casing being mounted as in a sash-rail,

the spur 26 is permitted to contact at desired points with the window-frame, thereby hold ing the sash in adjusted position and also producing an indention or depression in the window-frame, which may be used as a guide for boring a socket for the reception of the bolt when desired.

As shown, the key 29 is inserted with the bit between the diaphragm 1A and the disk 23 and when turned bears against each and forces the movable disk 23 to the position shown in Fig. 3, with the bolt 22drawn within the easing and held therein and thereby until the key is' manually turned backward. It will thus be seen that by turning the key 29 the bolt 22 is retained in the drawn position, and the window or other article upon which it is mounted is permitted to move freely. With, however, the key in the position shown in Fig. 4 the bolt is under tension of the spring 25 and arranged to engage an appropriatelydisposed socket.

Having thus described the invention, what is claimed is 1. A lock comprising a casing consisting of semicylindrical members one of which is provided with laterally extending anchoringflanges, diaphragms extending transversely of the casing and serving to lock said members together, and a bolt eccentrically mounted for sliding movement in said diaphragms.

2. A lock casing comprising semicylindrical members one of which is provided with a plurality of openings, spaced diaphragms secured to the opposite member and provided with lugs adapted to engage the openings in the adjacent member, one of said members being provided with lateral flanges along its longitudinal edges forming diametrically-disposed longitudinal beads externally of the casing.

3. A lock comprising a sectional casing secured together by spaced diaphragms provided with eccentric registering openings, a bolt slidably mounted in the eccentric openings and having a rigid disk, and a key arranged to exert pressure between one of the diaphragms and the disk to move the bolt.

4. A lock comprising semicylindrical casing memberssecured together by spaced diaphragms provided with registering eccentric openings, diametrically-disposed longitudinal beads formed externally of the casing, a bolt slidably mounted in the eccentric openings and having a rigid collar and disk, a spring arranged to hold the bolt normally at the outward extreme and the collar in contact with one of the diaphragms, and a key arranged to exert a pressure between one of the diaphragms and disk to move the bolt.

5. A look comprising semicylindrical casing members one of which has outturned flanges along its longitudinal edges and provided with a keyhole and spaced openings, diaphragms provided with eccentric openings and rigidly secured to one casing member and having lugs engaged within the spaced openings of the other member, a bolt slidably mounted in the eccentric openings and having a rigid disk at one end and an axial spur at the other with a rigid collar disposed intermediate the ends, a spring surrounding the bolt and bearing against the collar and one of the diaphragms and arranged to hold the bolt normally at its outward extreme with the collar in contact with one of the diaphragms and a key having a bit proportioned to pass through the keyhole and exert a pressure between one of the diaphragms and the disk and to move and retain the bolt at its inward extreme and with the spur within the lines of the casing.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
